Hello, If I start a second instance of kamailio by mistake, if the cfg file instructs it to listen to tcp ports, the second instance will exit with something like this: tcp_init: bind(7, 0x81b28ec, 16) on 127.0.0.1:5060 : Address already in
use
But if the cfg file only instructs kamailio to bind to udp ports, the
second
instance will not exit. Is this a bug?
I'm curious because if we start kamailio and a udp port is in use by
another
application (not kamailio), kamailio will exit with udp_init: bind(4, 0x819f274, 16) on 192.168.88.29: Address already in
use
Why is that so?
That behavior may be possible if kamailio is setting SO_REUSEADDR socket option for udp but not for tcp.
Thanks Luciano, I didn't know about that. And you are right. As we can see at udp_server.c:
setsockopt(sock_info->socket, SOL_SOCKET, SO_REUSEADDR , ...
